01. 概述

halcon是一款非常不錯的視覺類輔助設計軟件，它是由非常專業的MVtec公司全新推出的最新版本。在功能上擁有非常實用方便的機器視覺開發能力，其非常獨特的內部結構能夠很好的輔助各種機器的視覺功能，這樣不管是在醫學圖像上面還是各種圖像分析上面都能夠起到非常大的幫助，并且軟件內部搭在了非常先進智能的圖像算法能力，用戶們在制作各種產品的時候就可以節省非常多的時間，極大的提高了工作效率。在用途方面，它也有著非常廣泛的應用，能夠用于多個行業的使用，就比如形態學，測量圖像以及blob等等相關圖像領域。作為系列的最新版本，它不光是優化了許多內容還新增了一些非常便捷的功能，現在可以做到通過更加高級方便的算法來讀取條形碼，極大的加快了讀取速度。還對軟件的開發操作環境進行非常人性化的升級優化等等

02. 開發環境

Windows系統：Windows10

Halcon版本：HDevelop 19.11

03. Halcon源碼

* 讀取圖片文件 read_image (Image, 'fabrik')* 獲取圖片大小信息 get_image_size (Image, Width, Height)dev_open_window (0, 0, Width, Height, 'black', WindowHandle)

04. Halcon源碼導出方法

4.1 選擇文件–>導出

4.2 選擇導出相關設置

支持導出的方式有：文本文件、C文件、C++文件、VB文件和C#文件。

05. Halcon源碼導出為C++程序

5.1 導出文件選擇C++

5.2 導出之后，查看導出的C++文件
